How To Get Rid Of Fog On Windshield? Helpful Tips To Know

A foggy windshield makes it difficult to drive on busy roads. You can eliminate the fog by improving air circulation in your car, turning up the heat, checking your cabin filter, using the glass defrost function, and opening the windows. Also, consider cleaning the windshield regularly and using the wipers to prevent fog build-up. The most common reasons for fog on the windshield are excessive moisture, low temperature, and condensation. You can try the solutions or hire a professional auto glass repair service to remove a foggy windshield. 

Easy Ways To Fix A Foggy Windshield

Here are some tips that you can try to get rid of a foggy windshield: 

1. Set the temperature: Run your car’s air conditioning to remove warm, humid moisture from the air and prevent condensation on your windshield. If it’s hot outside, try leaving your air conditioning on its lowest setting to match the temperature outside the car. 
2. Increase the heat: Set your car’s heater to maximum. Hot air contains more moisture than cold air, so increasing the temperature can help remove the moisture that causes foggy windshields. 
3. Turn on the defrost setting: Your car’s defrost feature combats windshield fogging. Directing dry, warm air at your windshield helps evaporate the moisture that forms the fog, leaving you with clearer vision. 
4. Improve the air circulation: Turn off the recirculation function in your car. It allows the vehicle to draw in outside air and balance the temperature and humidity inside the car with the outside air, helping the fog dissipate faster.  
5. Keep the windows open: Open your car windows slightly for a few minutes to balance the temperature and humidity inside the car with the outside environment, reducing fogging. 
6. Use the windshield wipers: An easy way to remove fog on the outside of your windshield quickly is to use your car’s wipers to clear the condensation off your windshield.  
7. Clean your windshield regularly: As mentioned above, a clean windshield is less likely to fog up. Regular cleaning will keep your windshield cleaner and clear foggy glass by removing dirt and oils that can trap moisture.  
8. Check your cabin filter: A clogged cabin filter can affect your car’s heating and cooling system, leading to increased fogging. Checking it regularly and replacing it when necessary can improve air quality and reduce windshield fogging. 

Causes Of A Foggy Windshield

Here are some of the most common reasons that you should know:

• Moisture  

Moisture causes water to build up and turn into water vapor. You breathe in moist air, which escapes from your body in and out. Because of increased breathing, windshield fogging is even more of a problem when multiple people are in the car.

• Temperature

Temperature is important to maintain to avoid fog build-up. Warm air holds more moisture than cold air. Molecules do not hold onto water molecules. When the temperature of water increases, more water becomes gas than liquid. And when the air is warmer, there is more space between the molecules so that the water molecules can fit into that space.  

• Condensation 

When moist, warm air hits a car’s cold windshield, it condenses, creating condensation and causing a cloudy windshield, which usually happens in the early morning. It is also why, when you run your car’s air conditioner on a humid, warm day, condensation forms on the underside of your windshield where it comes into contact with the cold air. 

How Do I Clean A Foggy Windshield? 

Here are the best options to defog your windshield: White vinegar and water are easy ways to defog your windshield. Some people use a 10% vinegar-to-water ratio.  In some cases, you can also add alcohol to the mix. Pour the mixture into a spray bottle and wipe your windshield with a microfiber towel or cloth. Aerosol cleaners are one of the best choices to get your windshield as clean as possible. They contain no CFC propellants and are pre-mixed, so there’s no need to measure.  

You can go right with Mr. Clean Magic Eraser for a blurry windshield. Yes, it has an abrasive effect, but it will not leave any scratches on the surface of your windshield. Just submerge it in water and let it work. It does an excellent job of removing substances such as smoke residue and gases that have built up on your windshield.  

Conclusion 

Fog on the windshield can be dangerous while driving, often leading to accidents. However, you can prevent this by keeping your glass clean, maintaining suitable temperature levels, improving the airflow, checking the cabin filter, keeping the windows open, and using wipers to defog the windshield. Also, ensure that the cabin filters are clean and that the defogger function of your car is working properly. You can also hire professional auto glass repair services for help.
